Our products are manufactured to the highest possible standards and it is important to us that you are able to select the right product from our extensive range, which will suit your particular application. Why are there so many different types of geotextiles? - Because each application needs a geotextile with specific characteristics and which performs a different function. Weed Control Membrane This membrane needs to shut out as much light as possible but with good porosity and longevity to ensure a continued barrier against weed growth from below. For total weed control, this membrane needs a very small hole size, less than 35 microns, a light transmittance of less than 5% and allow air and water to pass through. The membrane will control all rhizome weeds, most bulbs and corns from penetrating from underneath. Stabilising & Separation Strength is the most important factor ensuring that subsidence does not occur at a later date. The membrane needs to have a CBR puncture resistance of minimum 950 N up to 1500 N, and a dynamic cone drop not greater than 40mm. Drainage The hole sizes are crucial in this membrane to continuing long term drainage and should be microns. This will prevent clogging and silting allowing a natural land drain to develop. This type of membrane is the catalyst to develop a natural land drain. 1 2

10 F.A.Q S F.A.Q S ULTRA Q: Is there a right way up to lay Weedcheck Ultra? A: No, it does not matter which way up it is laid. Q: How long will Weedcheck Ultra last? A: If being protected by a Mulch about 25 years. Q: Will Weedcheck Ultra prevent all weed growth? A: Weedcheck Ultra is designed to control all Rhizome weeds, those which develop in the soil and are the most difficult to control. These are weeds such as Mare s Tail, Japanese Knotweed, Couch Grass, Bermuda Grass, Ground Elder and in addition most bulbs and corns. Q: What is Surface Weeding? A: These are either Annual or Perennial weeds which arrive in seed either by wind or by birds. They will germinate and try to push their roots through the Weedcheck Ultra. They should be removed as soon as they are seen to avoid damaging the membrane. Example of these would be chick weed and bind weed which are extremely aggressive once active, but would have developed on top of the membrane and not penetrated from underneath. Roots developed on top of the Membrane. This membrane has not failed. Surface Weeds needs to be controlled as soon as they develop to prevent them growing through the membrane. Clean shoots through the membrane with no visible root growth, as in the picture above. This is an example of how many woven membranes may not prevent all weed growth from underneath because of the larger hole size. Q: Can I feed my plants through Weedcheck Ultra? A: Yes of course liquid feed is best but solid feed will break down and wash through Q: What type of Mulch is recommended? A: Clean aggregates, bark chippings and cocoa shell will protect your Weedcheck Ultra. It is not advisable to put any soil on top of Weedcheck Ultra as a mulch. Q: Can I use Weedcheck Ultra without a Mulch? A: Weedcheck Ultra is designed to be covered by a mulch. Q: Can I use Herbicides with Weedcheck Ultra? A: No problem whatsoever herbicides will not affect Weedcheck Ultra in either its performance or longevity Q: Can Weedcheck Ultra be used under vehicles? A: No, Weedcheck Ultra is designed only for pedestrian use. GROUNDCHECK EXTRA Q: I see some weeds growing in Groundcheck Extra topped areas - how is this possible? A: We do not recommended Groundcheck Extra for weed control as the hole sizes in the membrane will allow certain rhizome weeds, bulbs and corns to come through. We recommend the use of Weedcheck Ultra for total weed control. Q: Would you recommend Groundcheck Extra when constructing a land drain? A: We do not recommend Groundcheck Extra for any drainage applications. For drainage use Stratacheck. Q: Can it be laid any side up? A: Yes Groundcheck functions whichever way it is laid. Q: How long will it last? A: If covered with a mulch and not exposed to sunlight or frost for around 30 years PLUS Q: I want to put some turf directly onto imported soil? A: Imported soil, no matter what they say, is likely to contain an assortment of weeds. Tamp and level the soil and lay down Stratacheck, do not overlap, butt the edges like wallpaper. Lay the turf on top and the majority of weeds contained in the imported soil will never be seen. Q: Can i use Stratacheck Plus in my Horse Manège? A: It is the perfect geotextile for this purpose however, you must ensure that the horse s hoof does not come into contact with the Stratacheck. Ensure that the Stratacheck is always covered with 6 to 8 of top dressing
